A.2.2 Measuring a Single Analog Input Signal

A test to determine the evaluation board performance with a full-scale input signal can be performed once

the hardware and software are configured. The following describes testing of the system using a typical

full-scale input signal.

Connect a 1 kHz, -0.5 dB signal into the evaluation board’s analog input channel.

Select the Frequency Domain window by clicking on the Frequency Domain tab at the top of the screen.

Deactivate the Grounded Input FFT. Activate the Log Freq Scale button. Several windowing functions are

available. In this example, the Window Type has been set to Crystal 7-Term.
